Mario Galaxy 2 brings a lot of new ideas to the table for Mario. Especially in the way of new powerups. But as I kept playing this game it just didn't feel any different to me then the previous game in the series. It's fun, for sure. But it just feels like we've been there before.
I will admit, I didn't understand how this fits in with the first one's storyline. Is it 100 yrs after the first one or another way the story could have happened. This aside it is a great and fun game. I like the addition of yoshi and a playable Luigi. Although Luigi slide stop is a little much but he has always been my favorite over Mario. My one compliant is the prankster comets. A few of the prankster comet levels are ridiculously hard.
